Objective To evaluate the hemodynamic changes induced by local infiltration with different concentrations of adrenaline during endoscopic sinus surgery under general anesthesia using impedance cardiography (ICG) .Methods Sixty-nine ASA Ⅰ or Ⅱpatients of both sexes (37 males, 32 females) aged 18-60 yrs undergoing elective endoscopic sinus surgery under general anesthesia were randomized to receive local infiltration of nasal mucous membrane with 4 ml of lidocaine containing 20 ?g (group Ⅰ) or 40?g (group Ⅱ) or no adrenaline (group Ⅲ-control) . Hemodynamic changes were monitored by ICG. MAR, HR, cardiac index (CI), systemic vascular resistance index (SVRI) and acceleration index (ACI) were recorded before (baseline) and at 0.75, 1.5, 2.25, 3.0, 3.75, 4.5, 5.25 and 6.0 min after local nasal adrenaline infiltration.Results MAP was significantly decreased while HR increased at 1.5 min after adrenaline infiltration as compared to the baseline values in group Ⅰ and Ⅱ (P

Objective Prostate cancer is one of the most common cancer in males .The article was to investigate the expres-sion and clinicopathological significance of VEGF-C mRNA in prostate cancer , finding the molecular marker for early diagnosis and prognosis assessment of prostate cancer . Methods TaqMan real-time polymerase chain reaction ( PCR) analysis was used to detect the expression of VEGF-C mRNA in 3 prostate cancer cell lines(PC-3, DU145 and LNCap), 32 cases of prostate cancer (Pca) sam-ples and 15 cases of benign prostatic hyperplasia (BPH).Analysis was also made on the correlations of VEGF-C mRNA expression, clinicopathological features and prognosis . Results High levels of VEGF-C mRNA were detected in PC-3 ( 153 .31 ±26 .24 ) and DU145(194.62 ±41.36)compared to LNcap(1.00 ±0.00).The expression of VEGF-C mRNA in prostate cancer tissues was 3.43 folds higher than that in the benign prostatic hyperplasia tissues ([13.67 ±1.95] vs [11.89 ±1.63], P=0.004).The high expres-sion of VEGF-C mRNA in prostate cancer was associated with high Gleason score ( P =0.004 ) and lymph node metastasis ( P =0.015).In patients with high expression and low expression of VEGF-C mRNA, the 3-year survival rate was 12.5%and 40.0%re-spectively(P=0.033). Conclusion The VEGF-C mRNA expression may be related to the biological behavior of prostate cancer .It is suggested that VEGF-C mRNA can be used as a prognostic marker for prostate cancer .

Objective To explore the effect of transcription factor E2F1 on the apoptosis of small cell cancer line H446. Methods Plamid vector- mediated E2F1 small hairpin RNA (shRNA) was used to silence E2F1 in H446 cell. RT-PCR and western-blot assay were used to detect the expressions of E2F1 and Bcl-2. The apoptosis rate in H446 cell line was detected by flow cytometry assay. Result E2F1 protein was suppressed in shRNA1-modified H446 cell. Sgnificant difference of the apoptosis was shown between E2F1 shRNA1 group and the other two groups. Additionaly, the expression of Bcl-2 protein increased in E2F1 shRNA1-modified cell line. Conclusions E2F1 is highly expressed in H446 small cell lung cancer cell line. E2F1 promotes apoptosis of H446 through upregulating Bcl-2 expression.

Objective To investigate the ultrasound diagnostic value for nipple discharge disease by comparison with fiberoptic ductoscopy. Methods Fiberoptic ductoscopy and ultrasonic inspection were performed on fifty-seven patients with spontaneous nipple discharge,and the results were analysed. Results In all patients, 55 cases (96. 49 % ) were abnormal in high-frequency ultrasound inspection:27 mammary duct expansion(47.36%),19 occupying lesion with mammary duct expansion or cyst (33.33%),6 cystic echo ( 10. 52% ) ,3 only solid echopattern (5.26%) ,and 2 nothing found (3.51% ). In ultrasonic inspection,color and pulse Doppler signal were found in 7 cases. On the other hand, 26 galactophoritis (45.61%), 12mammary duct ectasia (21.05 %), 17 intraductal papilloma (29.82%), 2 breast carcinoma (3.50%) were diagnosed by fiberoptic ductoscopy. In all 19 cases with occupying lesion,ultrasonography's sensitivity was 52. 63% ,specificity was 89. 47%, misdiagnosis rate was 10. 50%, rate of missed diagnosis was 47.36%.Conclusions To nipple discharge disease, high-frequency ultrasound has high sensitivity, easy to find abnormal indication,but is not accurate enough in the diagnosis of smaller occupying lesion.

Objective To study the effects and mechanism of different administrations of atorvastatin on myocardial ischemia/reperfusion (MI/R) in rats.Methods A total of 160 male SD rats were randomly divided into five groups:sham group,MI/R group,atorvastatin of conventional dose (MI/R + N) group,atorvastatin of preoperative signal loading dose (MI/R+SL) group,and atorvastatin of preoperative continuous loading dose (MI/ R+ML) group.MI/R model was established in the rats.Myocardial infarction size was detected by Evans blue/ TTC staining.The activity of ATPase of cardiac muscle and the levels of serum IL-6 and TNF-α were detected by ELISA.The level of LVEF％ was detected by small animal ultrasound.Results Compared with MI/R+N group,MI/R+ SL and MI/R+ ML groups had significantly smaller myocardial infarction size (P＜0.05),higher activity of ATPase (P＜0.05),lower levels of serum IL-6 andTNF-α (P＜0.05),and more advancedLVEF％ (P＜0.05).However,MI/R+SL group and MI/R+ML group did not differ significantly in the above-mentioned parameters.Conclusion Atorvastatin of loading dose might alleviate MI/R injury by improving ATP metabolism of cardiac muscle and reducing abnormal expressions of inflammation factors.Meanwhile,the administration of preoperative continuous loading dose and preoperative signal loading dose of atorvastatin may not differ in protecting against MI/R injury.

Objective To explore the effect of chitosan on vascular smooth muscle cells inhibited proliferation from rabbit arteriovenous fistula and its mechanisms.Methods Established rabbit fistula model on carotid arteryinternal jugular vein.After 1 month cultured VSMCs with primary culture by tissue-pieces inoculation.Cultured VSMCs were divided into three groups:①normal control group.②FBS-treated group:cell were treated with 5％,10％,20％ for 48 h,respectively; established the model of rabbit VSMCs proliferation.③chitosan-treated group:VSMCs cultured with 20％ FBS were exposed to different doses of chitosan(10,100,500,1000,2000μg/ml) for 48 h.And VSMCs were treated for different time (0,12,24,48 h) with Chitosan 1000 μg/ml.Expression levels of PCNA and TLR4/ NF-κB were detected by Western blotting.RT-PCR were applied to measure the mRNA expression of PCNA and TLR4.The protein levels of TLR4 and NF-κB were detected by immunofluorescence.Results Compared with low concentration serum group,FBS-treated VSMCs exhibited a increase in mRNA and protein expression of PCNA and TLR4.FBS-induced protein expression of PCNA and TLR4/NF-κB were reduced by chitosan.Also mRNA expression of PCNA and TLR4 were reduced.They were dependent on concentration and time.In rabbit VSMCs TLR4 was mainly expressed in the cytoplasm and NF-κB expressed mainly in the nucleus.Compared with normal control group,TLR4 and NF-κB protein expression were significantly decreased by chitosan.Conclusion High concentration serum induced VSMCs proliferation.Chitosan can inhibit the proliferation of rabbit VSMCs.It is speculated that the mechanism may be related to the expression of TLR4 receptor activation,reducing expression of downstream factor MyD88 and NF-κB.It is suggest that chitosan can become potential new drugs of arteriovenous fistula prevention of intimal hyperplasia.

Objective To explore the diagnostic performance of susceptibility weighted imaging (SWI) in distinguishing malignant from benign parotid lesions.Methods We prospectively evaluated preoperative SWI findings of 41 patients with 12 malignant and 29 benign parotid lesions by surgical pathology, and explore the intravenous distribution, the largest diameter of veins (dv-max), the number of veins per unit area (N/Svein) and the graduation of intratumoral susceptibility signal intensity (ITSS).The parameters was analyzed by Chi-square test, Independent t-test, Mann-Whitney U rank test and receiver operating characteristics (ROC) curves with SPSS 16.0 software.Results (1) For intravenous distribution, the benign ones mainly distributed around peripheral areas, accounting for 89.7％ (26/29), while the malignant ones were centrally distributed, making up 10/12.There were significant difference (x2=20.882, P=0.000) between benign and malignant ones.(2) The largest diameter of veins (dv-max) of benign and malignant lesions were (1.1±0.5) mm and (2.5 ± 1.0)mm respectively.There were significant difference (t=4.633, P=0.000) between benign and malignant ones.(3) The N/Svein of benign lesions were (0.80±0.92) per cm2, while that of malignant ones are (1.07±0.69) per cm2.The N/Svein (t=0.9143, P=0.367) was statistically insignificant.(4) For the graduation of ITSS,among benign lesions, there were 3 cases of grade 0, 22 cases of grade 1, 2 cases of grade 2 and 2 cases of grade 3.Meanwhile, there were 2 cases of grade 1, 5 cases of grade 2 and 5 cases of grade 3 among malignant lesions.When the Youden index reached the highest point, the optimal diagnostic threshold of dv-max and ITSS values were 1.75 mm and 1.5 mm, the corresponding area under the ROC curve (AUC) were 0.924 and 0.856 respectively.The sensitivity of d and ITSS ondiagnosis were 10/12 and 10/12, and the specificity of that were 96.6％ and 86.2％ respectively.The table shows that the sensitivity and specificity of intravenous distribution in diagnosis of malignant lesions are 10/12 and 89.7％.Conclusions The results provided evidence that SWI may be helpful in distinguishing malignant from benign parotid lesions, and it is worth to be generalized in clinical medicine.

Objective To explore main technical points and clinical efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis. Methods To retrospectively analyze materials of 103 patients treated by individualized stepwise multiple embolization. According to disease categories, individualized stepwise multiple embolization treatment with polyvinyl alcohol and loaded sodium alginate microspheres as basic embolization agent were performed, after the type, number, abnormal branches, pulmonary circulation and systematic pulmonary shunt of targeted vessels were confirmed through radiography. To judge short(less than 3 months), medium(3 to 6 months) and long term(more than 6 months) efficacy, resolution of hemoptysis after operation were assessed. To evaluate efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis, Kaplan-Meier survival curves were used. According to the features of target vessels to supply blood, patients were classified into with SPS and without SPS. By using Log-Rank test, the effective rates of one-year were compared between them. Results Out of 103 patients, 215 target vessels were demonstrated, among which individualized stepwise multiple embolization was for 196 target vessels, peripheral embolization for 8 vessels, and main trunk embolization in 11 patients. The visits after operation were made to 103 patients after 6 to 50 months, with the medium of 21 months. Hemoptysis was instantly resolved in 97.1%(100/103). The effective rates were 94.5%,93.2%, 89.7%,88.9%,85.2%and 76.6%for one, three, six months and one, two and three years after operation. In 103 patients, patients with SPS were 22 and without SPS were 81. One-year effective rates with and without SPS were (69.50 ± 0.11)% and (98.30 ± 0.03)% , respectively (χ2=11.662,P<0.01). Conclusion Individualized stepwise multiple embolization treatment shows excellent short-term and mid-long term efficacy in the treatment of refractory hemoptysis.
